装置が一定量の膨張ガスを提供して封絶体を膨張し1、
これが乗物の乗員を抑止する。A collision signal from the sensor activates an inflation device which provides a quantity of inflation gas to inflate the seal 1.
This deters the occupants of the vehicle.
ここに述べる種類の安全装置は乗物の客室内で展張する
ために計器板内又は操向バンドル上に設けられる。Safety devices of the type described herein are provided within the instrument panel or on the steering bundle for deployment within the cabin of the vehicle.
この発明は任意の安全装置に等しく適用可能であるが、

運転者は計器板よりも操向バンドルに接近して着席して
いるから、操向バンドルの封納体は一層短時間内で十分
に膨張される必要がある。Since the driver is seated closer to the steering bundle than the instrument panel, the steering bundle enclosure must be fully inflated within a shorter period of time.

止する封納体の能力を損じ、また膨張に時間がかかると
いう欠点がある。However, if the expansion force acts on the enclosure only in the direction of the driver, the enclosure may collide with the driver and cause injury.
On the other hand, if the expansion force acts on the enclosure only outward in a direction perpendicular to the driver's direction, the force will suddenly build up on the peripheral attachment part of the enclosure, causing it to break. This has the disadvantage that it impairs the enclosure's ability to inhibit the growth of gas, and that it takes time to expand.
したがって、この発明の目的は、操向バンドル上に取付

火薬導火剤は推薬60よりもさらに速かに着火するから
、火薬導火剤は膨張装置の全周を囲んで着火され、その
結果推薬60の周囲に均等に着火する。Since the gunpowder fuse ignites more quickly than the propellant 60, the gunpowder fuse is ignited around the entire circumference of the expansion device, so that the ignition is evenly distributed around the propellant 60.
推薬60が燃焼すると封納体を膨張するのに必要なガス
が発生され、膨張装置内及び噴出孔48内のガス圧力は
徐々に生成されて、拡散部材50の下側に力を作用する

由に流出するが、そのまま軸方向に(第4図で上方へ)
移動し続けずに、拡散部材50aによって押えられて点
線矢印で示すようにほぼ半径方向外方へ誘動される。When the diffuser 50 is deformed, the expanded gas flows freely out of the nozzle 48, but continues to flow in the axial direction (upward in FIG. 4).
Instead of continuing to move, it is held down by the diffusion member 50a and guided approximately radially outward as indicated by the dotted arrow.

極減させることがわかる。Referring to FIG. 2 along with FIG. 4 again, the diffusion member 50 expands in this way, and as a result, the expanding gas flows almost in the easy direction, so that the expanding force acts only in the direction of the driver. , minimize the possibility of injury due to the impact of the enclosure to the driver, damage to the enclosure due to expansion force acting only in the radial direction of the enclosure, or the need for a long time for expansion. I understand that it can be done.

b) an actuating member that is actuated in response to a collision signal to actuate the fluid source; (C) an actuating member that is surrounded by an enclosure to contain a source of inflation fluid and to contain the inflation fluid generated from the source; (d) a casing having a spout orifice that spouts into the housing; (d) a first position disposed over the spout of the casing to seal the spout when the source of inflation fluid is inoperative; Sometimes, the pressure of the inflation fluid generated from the source of inflation fluid causes the orifice to deform toward a second opening position, and this deformation directs the inflation fluid ejecting from the orifice into the enclosure and aligns the orientation of the orifice. A diffusion member made of a hard flexible plate that guides diffusion in substantially orthogonal directions. 2. Inflates an inflatable enclosure for restraining vehicle occupants in response to a collision signal, which comprises the following members (a) to
(e) An expansion device for a vehicle safety device, comprising: (a) a casing having a substantially circular cross section; (b)
a propellant housed in the casing and ignited to generate high-pressure expanding gas; (c) an ignition member attached to the casing that ignites the propellant in response to a collision signal; (d) jetting out high-pressure expanding gas. (e) a lid member of the casing having a nozzle orifice which is disposed over the nozzle of the casing lid member and is in a first position to seal the nozzle when no inflation gas is generated; , is deformed by the pressure of this expanded gas toward the second position where the nozzle is opened, and due to this deformation, the expanded gas ejected from the nozzle is diffused and guided in a direction substantially perpendicular to the direction of the nozzle, and the enclosure is A diffusion member made of a metal plate that has a part designed to expand.
